1. What It Is: EN590 is the European standard for diesel fuel used in road vehicles. It defines the physical and chemical properties of diesel to ensure engine compatibility and low emissions. The most common form today is ULSD (Ultra-Low Sulfur Diesel).
2. Sulfur Levels:
EN590 can be produced at different sulfur levels, though modern regulations favor ultra-low sulfur:
Sulfur Content
Description
Compliance Standard
10 ppm
ULSD (most common today)
Euro 5 / Euro 6
15 ppm
ULSD (US EPA standard)
EPA ULSD spec
50 ppm
Low sulfur diesel
Euro 4
500 ppm
High sulfur (phasing out)
Pre-Euro 4
1000–5000 ppm
Off-spec, industrial use
Not for road vehicles
3. Key Specifications (EN590:2013 or latest):
- Cetane Number: Min 51
- Density @15°C: 820–845 kg/m³
- Flash Point: Min 55°C
- Viscosity @40°C: 2.0–4.5 mm²/s
- CFPP (Cold Filter Plugging Point):
- Summer: max +5°C
- Winter: down to −20°C or lower
- Aromatics: Max 11%
- Sulfur: Based on grade (see table above)
4. Applications:
- All modern diesel vehicles (cars, trucks, buses)
- Compatible with Euro 4, 5, and 6 engines
- Also used in generators and light machinery
5. Environmental Compliance:
- EN590 10 ppm diesel is designed to reduce particulate matter, SOx, and NOx emissions
- Essential for vehicles equipped with DPF (diesel particulate filters) and SCR (Selective Catalytic Reduction)
6. Market Notes:
- EN590 ULSD 10 ppm is standard in Europe, UAE, Singapore, and many export markets
- Delivered by truck, rail, or vessel under FOB, CIF, or DDP contracts
- Often requires SGS inspection at port
